Now that we know why subject lines play an important role, let’s look at the different types of subject lines for your abandoned cart email templates.

The 7 Types Of Abandoned Cart Email Subject Lines

Before you pick your brain, here are a couple of tried and tested formulas that can help you craft the perfect abandoned cart email subject lines.

1. ‘Forgot Something’ Subject Lines

This is one of the most common styles of subject line that integrates a well-known sales trope – the assumptive close. This favorite sales technique assumes that the shopper is willing to buy the product and has already made their mind, but was interrupted while checking out. It ignores the other conditions that might have caused such action. Thus, if you’ve ever left a product in your abandoned cart without checking out, you might have undoubtedly received an email with a subject line like:

  • Did you forget [Product]?
  • Did you forget something? Casper, MCM
  • You left something behind. Moschino
  • Heading out without checking out? Huckberry
  • Ooops, you forgot something. J Crew

Bonus Tip: ‘Forgot Something’ Subject Line template

With these subject lines, the message is centered around reminding the shopper that they still haven’t completed the purchase. Here are a few words that you can use to frame a perfect subject line:

  • Oops
  • Complete
  • Come back
  • Forget
  • Finish
  • Leave
  • Forgot
  • Left

And here’s how these words could fit into subject lines: 

  • Ooops, get what you forgot 
  • Looks like you forgot something, complete your purchase
  • Get back here to complete your checkout 
  • Did you forget to checkout [Product]
  • Ready to buy? Complete your order now
2.  ‘Incentivized’ Subject Lines

Shoppers abandon shopping carts for all kinds of reasons. Two of the biggest reasons are shipping costs and prices. Now, to sway your shoppers to complete their purchase, a subject line that addresses their reasons helps you recover the revenue. That’s why, if you feel shipping costs are a concern, address the problem right in the subject line for the abandoned cart email. Likewise, if it’s for different price points, try to experiment with discount offers in the subject line to get the best results.

But, to nail your subject lines in this style, deep-dive research on what is forcing your shoppers to abandon the cart, can help you figure out the best reason to address.

3. ‘FOMO’ Subject Lines

The FOMO (Fear Of Missing Out) is one of the best sales tactics, a marketer can use. This not only induces a sense of urgency but also a fear of something big. So, marketers often take resort to this to tell shoppers what they are missing if they don’t buy the abandoned product. It also builds a sense of scarcity which also plays a very important role in boosting the email open rates of an abandoned cart email. 

When a shopper leaves an in-demand product in their cart, Google sends an email with the subject line: ‘The [Product] in your cart is going fast’.

5. ‘Product-Related’ Subject Lines

Product-related copies in your abandoned cart email subject line can help remind shoppers why they like your brand and the reason they wanted to purchase from you.

6. ‘Brand-Related’ Subject Lines

With endless products and emails coming their way, a gentle reminder for your shoppers can work like a charm. Another good tip is to mention the product right in the subject line to remind your shoppers why they had added the products to their cart in the first place — and most importantly why they were keen to purchase.

As an example, 23&Me, uses “Your DNA kit is waiting for you” as the subject line for their abandoned cart email while some brands like Ralph Lauren use brand names in their subject line. Using brand names right in the subject-line conveys quality and adding the brand name to the subject line helps shoppers to remind them why they wanted to buy from you specifically.

Here are a few subject lines that several brands use:

  • Dyson uses “Items in your basket at dyson.com”
  • Ralph Lauren uses “Finish Your Order at Ralph Lauren”
Best Hacks

Use your brand name and other ways to weave the perfect subject line:

  • Your [Product] is waiting in the [Brand Name] store
  • Your [Brand Name] Products are in your basket
  • Complete your [Product] purchase at [Brand Name]
  • Complete your purchase with [Brand Name]
7. ‘Nudge’ Subject Lines

Every Target audience is different. For some businesses, the ‘Forgot Something’ trope will work, while for others, you might just want to nudge your shoppers a bit and be a little blunt on how you ask them to complete their purchases. 

Before fixing on best subject lines for abandoned cart email, you should remember that once a product has been added to the cart, the shopper has done:

  1. Researched about the product
  2. Went through your eCommerce website and decided what they wanted
  3. Committed to adding the product to the cart

However, due to some unfortunate obstructions, they might just miss completing their purchase. And sometimes, all you need is just a reminder to push them over the finish line.

One such example of this trope is very well used by Virgin Atlantic who uses the subject line ‘You’re nearly there’ to remind the shopper that they’re just a few steps short from booking their dream trip and enjoying their dream vacation.

Nudge Subject Lines
Best Hacks

This style of subject line demands you to be subtler than the other styles. Here are a few tips:

  • They’ve already done the hard work
  • With easy steps, the checkout will just take a few minutes
  • Access to rewards once they complete checkout (a dream holiday, best cooking utensils, or a great sleep cycle for a mattress, etc.)
